THE CLIMATE AT THE SOUTH POLE IS THE COLDEST IN THE WORLD. CAN ANYONE GUESS HOW COLD IT GETS AT THE SOUTH POLE?
DURING THE SUMMER, THE HIGH TEMPERATURE AVERAGES -26 DEGREES CELSIUS, OR -15 DEGREES FAHRENHEIT. DURING THE WINTER, TEMPERATURES REGULARLY GET DOWN TO -58 DEGREES CELSIUS, OR -72 DEGREES FAHRENHEIT. IN COMPARISON, THE TEMPERATURE OF THE AVERAGE FREEZER IS -18 DEGREES CELSIUS OR 0 DEGREES FAHRENHEIT
These conditions also mean that you need more energy when taking long expeditions to the South Pole. How do you think South Pole explorers get that extra energy?
The amount of energy that foods produce is calculated in calories. The average adult needs to eat about 2400 calories to maintain his or her current weight. South Pole explorers need to eat around 6000 calories a day to keep their energy at the level that it needs to be. 2400 Calories6000 Calories
What kind of food would you bring to the South Pole?
Because of the cold conditions, food at the South Pole regularly freezes over. It can take from several hours to days for food to thaw completely. The weather can also make it very difficult to prepare food. Because of this, some South Pole explorers use a dried meat product called pemmican to keep their energy level up. Since pemmican does not freeze or require a lot of preparation and it does have a significant amount of calories, it is the perfect food for South Pole explorers.
